IPv6 has enough addresses to use a different address for every outgoing connection. NAT buys you nothing and is only a horrible dumpster fire.

  IPv6 gives you a ridiculously large number of different IPs... but they are all in the same /64, which you can pretty much treat as a single location. So, all these IPs aren’t really adding much to protect someone’s privacy.

    The claim was that it made it worse. How is sharing the same /64 worse than sharing the same IPv4 address? On top of that, you don't actually know that it's a /64. The customer could have a /56. The customer could have a /128, which some mobile ISPs do. The customer could have a /128 with the ability to request arbitrarily many of them from the ISP, allowing the same trick with one IP per outgoing connection but causing the pool to be shared across all the ISP's customers. The ISP could, in principle, allow the customer to request an arbitrary number of non-contiguous address ranges of an arbitrary size and use them for an arbitrary duration before reassignment to a different customer. Nothing really requires it to be a single /64 forever.

      1. it forces the banning of a larger group of people because there are more people than addresses 2. its impossible to uniquely globally tag each person with an ip
